Metal Lapping, aluminum, copper polishing and stainless steel

Precision Metal Lapping and Polishing

Precision metal lapping, polishing, finishing and sizing to tight tolerances of all
types of metals is our specialty.
Whether it is Stainless Steel, Aluminum, Hastelloy, Titanium Carbide, Brass
or Molybdenum, we can do it all. No parts are too large, small, thin,
soft, or hard.

Valley Design
continues to expand its role as a precision metal lapping and polishing facility for
ultra-flat metal components requiring tight tolerances. Flatnesses to 1/4 lightband
and parallelism to 50 millionths of an inch are achievable at Valley Design.
We process materials such as Stainless Steel, Aluminum, exotics, plastics, and
Ceramics using planetary, double disk, and free abrasive lapping machines. Valley
has the capability to process parts as small as a few thousandths of an inch
and up to 32 inches and larger in diameter.

We also repair vacuum
chucks when worn or damaged. With prior notice, 24 hour service may be possible.
